Product Overview

The Allen-Bradley 1761-NET-AIC, commonly known as the AIC+, serves as the essential bridge for networking legacy MicroLogix and other SLC-based controllers. This 100% Brand New advanced interface converter facilitates seamless protocol conversion between RS-232 and DH-485. It allows multiple devices—including controllers, HMIs, and PCs—to share a single DH-485 network. By providing isolated RS-232, RS-422, and RS-485 ports, the 1761-NET-AIC eliminates communication barriers in complex multi-drop or point-to-point industrial architectures.

Technical Specifications

The 1761-NET-AIC utilizes high-grade optical isolation to maintain signal integrity across diverse network nodes.

Engineering Advantages

• Protocol Flexibility: This module converts standard RS-232 signals into the DH-485 protocol. This allows modern programming terminals or PanelView HMIs to interface with MicroLogix 1000, 1200, and 1500 controllers without proprietary cable restrictions.

• Superior Optical Isolation: The 500V DC internal isolation protects your controller's sensitive logic circuits from ground loops and electrical noise common in long-distance RS-48
